Manchester United boss Jose Mourinho is eyeing Barcelona winger Ousmane Dembele.
Don Balon says United are keen to bring Dembele to Old Trafford.
Mourinho is prepared to use Anthony Martial as a makeweight in a swap deal.
The forward has struggled for regular game time since the January arrival of Alexis Sanchez from Arsenal.
Martial wasn’t included in France’s squad for the World Cup and he has been linked with Chelsea and Bayern Munich as he seeks a fresh start.
